[A cooperative study on the incidence of bacteriuria in patients with benign prostatic hypertrophy]

The incidence of bacteriuria in patients with benign prostatic hypertrophy was studied at 8 National Hospitals. Among 1,542 patients, urinary infection was the reason of visit in 63 patients (4.1%). After open and transurethral prostatectomy, one-third of patients developed bacteriuria (30 of 59 subcapsular enucleations, and 252 of 776 transurethral resections). When a catheter is placed without prophylactic antimicrobial, all patients developed bacteriuria within 10 days, and within 30 days even if they received antimicrobials. The incidence of bacteriuria increased with age.
